This study wIll make you think twice about who you are getting into bed with.

These days you have to be wary of who you sleep with as a study has shown that women could potentially carry the DNA of previous partners. A group of scientists has found out that a minority of women have Y-chromosome gene sequences in their blood that men usually have. This is significant find as it allows us to speculate as to how they managed to get them. Be careful who you sleep with An obvious assumption to make is that from a pregnancy with a male son, every woman would still carry those cells within her bloodstream. Furthermore the conclusion from this is that these Y-chromosome cells would reside within the mother's bloodstream for the rest of her natural life regardless of miscarriage or termination. Microchimerism is the medical term for this condition which got the name after the mythical, monstrous Greek chimera that appeared to be three animals rolled into one. A lion, snake, and a goat! Sex transfers DNA of partners A study then needed to be commissioned to understand if women without sons could still be expected to carry y-chromosomes in their blood. The study in question was conducted by immunologists at the Fred Hutchinson Cancer Center who took samples from 120 women who had never given birth to sons and found out that these women had 21% male DNA! Sexual Baggage The conclusion that was drawn from this study is that from intercourse alone there is potential for women to hold onto male DNA from their sexual partners for their entire life regardless of having more or fewer kids.
